I have not done any floor sanding w/Festool sanders, but i do have a word of warning to any who may not be familliar with a serious hazzard. I'm sure that this is not a common problem with general shop work as it is more common to wait for first applicated finish to thoroly dry before second application. When pro finishers do a floor, they apply one coat and go to next one or more jobs, not coming back for atleast a couple of days. by that time, the finish has cured before sanding. i have seen it happen with homeowner where they sanded too soon. the finish had not totally cured. They left the sanding in a five gal bucket on the outside porch, thinking they would further dispose in the AM. Sometime in the nite, they were notified by police that their brandnew house was gone. The sanding dust had heated in the bucket and eventually, spontaneous combustion took the front stage.
as my kids were growing up, i used to harp on leaving oil soaked rags, wet wood dust, wet hay, etc, etc in closed (or even with tops off) containers or buildings. I nearly always got grumbling with the common (among every teenager in the world) expletives about stupid grownups when i went into my tirades. when the above house burned down, my son made a special trip (15 miles between homes) to show me the news article before i got to see it first. I'm an early riser, so he was late. I was, however, E-late-d over the fact that all of my preaching had finally sunk in. I'll continue to preach.
